Primary nutrients:
- Anthocyanins: Reduce inflammation and protect brain cells in aging dogs
- Vitamin C: Strengthens immune response and collagen production
- Vitamin K: Supports blood clotting and bone metabolism
- Manganese: Powers enzyme function and nutrient processing
- Fiber: Acts as a prebiotic, feeding beneficial gut bacteria that influence immunity and behavior

How to Safely Prepare and Feed Blueberries

Wash fresh blueberries for 30 seconds under running water, or choose plain frozen varieties without added ingredients; avoid all blueberry-flavored products containing xylitol.
Preparation guidelines:
✓ Fresh: Rinse thoroughly; organic reduces pesticide exposure
✓ Frozen (plain only): Check labels for single ingredient—excellent for teething puppies
✓ Cleaning boost: Soak in 1:3 vinegar-to-water ratio for 5 minutes, then rinse
Never feed: Dried blueberries (concentrated sugars), canned varieties (syrups), baked goods (toxic ingredients), or treats with artificial sweeteners
Wild vs. store-bought caution: Wild blueberries risk toxic lookalikes like nightshade berries and pesticide contamination near agricultural areas. Store-bought berries from regulated sources eliminate misidentification dangers and provide consistent quality.

High-risk categories:
- Toy breeds (Chihuahuas, Yorkies): Small airways increase choking potential
- Brachycephalic breeds (Bulldogs, Pugs): Flat-faced anatomy heightens aspiration risk
- Gulpers: Dogs who swallow without chewing
Prevention strategies:
✓ Supervise first feedings closely
✓ Mash or halve berries for dogs under 10 lbs
✓ Freeze berries in puzzle toys to slow consumption
✓ Never exceed weight-based recommendations
Overfeeding symptoms: Vomiting, diarrhea, stomach upset, and excessive calorie intake leading to obesity.
